[Also in Division G5] A device for plotting the ground track of a satellite comprises a globe 11 (Fig. 1) mounted for rotation about a polar axis 14 and carried in a frame 13 in relation to a chart table 19, and a cursor 22 mounted to be turned in the plane of the table 19 about an axis through the centre of the globe and means defining a line 25 radial to the globe and parallel with the plane of the table. The globe 11 is mounted in a well in the table 19 for rotation in bearings on a ring 15 rotatable in the plane of the frame 13 by a handle 16 and clampable thereto by clamps 17. The frame 13 is secured to the table 19 at 18. The cursor 22 may be rotated about a fixed guide ring 23 and carries a lamp and lens box arranged to direct a spot of light radially on to the globe 11. A crank handle 26 allows rotation of the globe through suitable gearing which also drives clocks 31 indicating the angle through which the globe has been turned in terms of days and hours. A chart is compiled from the calculated orbit of the satellite showing the angular relationship of any point on the orbit in relation to the globe at various times from perigee, and this chart is placed on the table 19 with the cursor 22 over it. To plot the sub-satellite point for a certain time the axis 14 is set at the desired angle and the globe is rotated through a distance corresponding to this time. The cursor is set on the appropriate time mark on the chart and the spot of light on the globe gives the sub-satellite point. If desired, the globe 11 may be rotated by hand against frictional restraint and the chart and chart table may be of annular form. In a further embodiment, Fig. 2, a globe 42 is mounted for rotation about an axis 43 by a handwheel 48, the angular position of the globe being determined by a scale 51 and painter 52. The globe is carried in a frame 44, which is clamped by clamps 46 in a holder 45 to set the axis 43 at the desired inclination, this being indicated on a scale 47. A base 41 is provided and this is mounted on a chart compiled as before. A hub 55 on the base carries a cursor 57 moving over the chart and a pencil 53. The globe is set and rotated as before, the sub-satellite points being marked by the pencil 53. The chart may be mounted for rotation to allow for the inclination of the orbit relative to the median plane of the globe.

Abstract: 774,418. Sheet-delivery apparatus. BEASLEY, FRENCH & CO., Ltd., and FRENCH, G. W. Sept. 14, 1955 [Sept. 16, 1954], No. 26869/54. Class 100(1) A machine for delivering bags or the like including a top 'and bottom folding roll is characterized by means adjacent the bottom folding roll for applying a braking action to the velocity of a bag so that the bag continues its travel to base plate or stop at a reduced velocity, spring gates being provided for holding a batch of delivered bags adjacent the bottom folding roll and so arranged that as a bag is delivered from the roll the article of the batch remote therefrom is released to a stack. As shown the machine includes a top folding roll 1. a bottom folding roll 2 having grippers 3 and grippers 4, and a presser roll 5. Dabbers 6, for slowing down the delivery of a bag 7, are mounted on frames 8 pivoted at 9 and consist of a base 10, adjustable along a track 12, and a resilient pad 11. The swinging movement of the frame 8 is controlled by cam segments 13, having faces 14 coacting with a roller 15 on arms 16, which 'are pivoted at 17 to the frames 8. The roller 15 is held against the cam face 14 by a spring 18. The dabber 6 operates on the tail end of the bag after it is released by the grippers so that the leading edge of the bag strikes a stop 19 at reduced velocity before delivery against a support 20 on a carriage carried by moving tapes 21 running on a table 31. The tapes 21 are operated by a ratchet operated roll 22 actuated through linkage 23, 24, 25 by a roller 26 controlled by an eccentric ring 27 on the roll 2. The carriage comprises a trolley 32, to which is secured the support 20, and which has roller 32 running on the table 31. Arms 36 and 37 are pivoted at 34 and 35 so that on actuation of arm 36 by a hand arm 41 belt gripping surfaces 42 on both arms 36, 37 are released from engagement with the tapes 21 and the carriage may be moved back against the direction of movement of the tapes. For holding a batch of delivered bags adjacent the roll 2 spring gate 43 mounted on plates 44 are secured to blocks 46 mounted on the frame of the machine, the arrangement being such that as a bag is delivered from the roll 2 the outer bag of the batch is released to the stack. The spring gates 43 are made in the form of spring steel fingers. The delivered bags may be counted and the batches separated by displacing a bag 7a at predetermined intervals. To this end an arm 51 is periodically lowered by a cam mechanism and gearing operated from the roll 2. When the arm 51 is lowered a linkage 56, 58 raises the arm 16 so that the cam 14 contacts the roller 15, and thus operates the dabber, earlier than normal. At the same time an arm 59 moves the strippers 4 upwardly so that the bag is freed earlier.

Abstract: 337,883. Hoseason, D. B., and Associated Electrical Industries, Ltd. Sept. 4, 1929. Dynamos and motors, cooling.-The rotor or stator core of an air-cooled dynamo-electric machine is provided with one or more spaces between its ends communicating with ducts on each side through which air passes, the ducts being staggered with respect to each other on the two sides of the space so that the entering air impinges on imperforate parts of the core and thereby has its direction of flow abruptly changed. In addition, other spaces may be provided in the core into and from which air enters and leaves at opposite sides through ducts which are collinear so that some of the air passes in one direction through these spaces to the space or space having staggered ducts. In the form shown, the rotor laminae 1 are divided into three packets separated by spaces 11, 12 into which cooling air passes axially from both ends of the machine through core ducts 9, 10. The ducts on the two sides of the space 11 are staggered, so that the air entering the space from both sides is sharply deflected out radially, and those on the two sides of the space 12 are in alignment so that some of the air passes through to the space 11 and some passes out of the space 12 radially. The space 11 is placed near to the commutator end of the rotor for disposing of the greater heat which is produced in that region in some types of machine.

Abstract: 1,135,785. Telephone exchanges. INTERNATIONAL STANDARD ELECTRIC CORP. 17 June, 1966 [19 June, 1965], No. 27101/66. Heading H4K. A detector AE, employed for sensing the condition of a line loop connected to terminals AB, is back biased relative to exchange battery U and feed resistors RS1, RS2, by means of battery potentials Ua, Ub, or resistors such as R1, R2. As loop resistance decreases the voltage across the detector AE decreases from an initial negative value to zero from which it progresses to increasing positive values. A number of detectors AE1 to AEn, as shown, can be employed so that the switch from negative to positive voltage on each detector takes place for progressively different loop conditions, or so that, with different loops presented a different detector can be chosen for each loop, each detector operating at the same current threshold. The detector may be a transistor or a simple diode sensed in an A.C. circuit.

Title: Improvements in electric driving and controlling gear for planing machines
IPC: B23Q15/007
Filed: 1919-11-06
Abstract: 160,209. Electromotors, Ltd., Longbottom, B., and Greenhalgh, E. Nov. 6,1919. Systems controlling reciprocating motion of planing-machines; systems for continuous-current motors only.-A system for one or two motors driving a planing-machine under the control of a tappet switch operated by the planer-bed has main and reversing contactors controlled by the switch, a contactor or contactors cutting out the starting or current-limiting resistance, and contactors controlling the insertion of field-resistance regulators into the field circuit, the operation of which is dependent upon one of the starting resistance contactors and the reversing contactors so that the field cannot be weakened until both these switches are closed. The starting resistance may be arranged in sections upon each side and the armature and the starting resistance contactors may be controlled by a switch opened by an overload coil in the main circuit so as to resist resistance if the current should exceed a prescribed maximum. The system comprises main contactors A, A<1> reversing contactors H, H<1>, starting resistance contactors E, E<1> field resistance regulators R, R' and their corresponding contactors O, O<1>. It is controlled by switches b<1>, b<2> and the planer tappet switch B with two positions. When the switch b<1> is closed the main contactors A, A<1> are closed, the actuating coil a being excited directly and the coil a<1> indirectly through a contact a<6> made by the contactor A. The circuit of the coil a<1> of the contactor A<1> includes the tappet switch K and is opened at each reversal of this switch. It may also be opened by the switch b<2> to stop the machine which action also opens the circuit of the coil a of the contactor A. The starting resistance contactors E, E<1> are energized in sequence by the contact a<1> made when the main contactor B<1> closes, the overload switches D, D<1> causing either to open to reinsert resistance should the current on the armature circuit exceed a predetermined value. The last contactor to close, namely E, has two switches g<1>, g<2> coupled to it so that they are both opened when the contactor E is closed and vice versa. The reversing contactors H, H<1> are directly energized by the tappet switch K, one in each position of the latter. To each reversing contactor is coupled a switch g<3>, g<4> which is closed when its contactor opens and vice versa. The yield N includes in its circuit two regulating resistances R, R<1> adjusted to give motor speeds appropriate to cutting and return strokes. These regulators are short-circuited by contactors O, O<1> the actuating circuits of which are so connected to the switches g<1>, g<2>, g<3>, g<4> that they are both maintained complete until all starting resistance has been cut out and then only the circuit of the contactor appropriate to the particular reversing switch which is closed is deenergized. The system for two motors, one for the cutting and the other for the return stroke, has similar features.
